Twenty years after Saigon fell to the North Vietnamese, former President Bill Clinton announced the normalization of diplomatic relations with Vietnam.

“This moment offers us the opportunity to bind up our own wounds," Clinton said, evoking words used by Lincoln at the end of the Civil War. "They have resisted time for too long. We can now move onto common ground."

Normalization had begun a year earlier in 1994, when the United States lifted a 19-year-old trade embargo against Vietnam in response to Vietnamese cooperation in accounting for the 2,238 Americans still listed as missing from the war.

Despite the move, high tariffs remained on Vietnamese exports pending the country’s qualification for “most favored nation” trade status, which Vietnam might earn after broadening its program of free-market reforms.

Republican Senator John McCain of Arizona advised Clinton in making the 1995 decision. McCain was an ex-navy pilot who had spent five years as a prisoner of war in Hanoi during the Vietnam War.

Brushing aside criticism of Clinton’s decision by some Republicans — most notably then majority leader Kansas Senator Bob Dole of Kansas (R), and other Republicans — McCain asserted that it was time for America to normalize relations with Vietnam.
